Be it known that I, HART, a citizen of the-U11 RAYMoND N. vEH1:- ited States, residing at Edgewood, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement of which the following exact description, reference being had to the accompanying drawings,

this specification. The present in Condensers,

is a full, clear, and

forming part of invention relates broadly to condensers, and more, particularly to condensers of the jet type,

although certain features of the construction are equally adaptable to general condenser work with condensers of other types.

In accordance with my lnvention, means of improved character are provided for permitting access to the water-injection nozzles and to the condensate pump.

In the drawings, the figure of which represents more or less form'of condenser in vertical section,

is disclosed a steam inl rounding water box 3.

that its bottom wall forms a surrounding overhang. tervals with hand holes This overhang is provided at in- 6, each of which is closed by a hand hole plate or cover/7, se-

covers. To overcome this difficulty, I provide a suitable lug or bracket 13 on the in termediate section 14 of the condenser, in c which there is journaled a' pulley 15. A line or cable 16 can readily be run over this pulley and down to an eye-bolt 17 on the pump cover 11. This line can be carried or in fact, in almost any convenientcdirection, to a block-and-tackle. The cover may therefore be easily raised out of position, a comparatively slight pull on thev line 16 serving sary outward movement of the cover. After the cover has been removed, the same pulley can be used to advantage in the removal of the pump shaft. i

Access to the interior of the cover may be gained through a suitable man hole 18, closed by the usual cover plate, and vapors may be withdrawn from the condenser through a 1925, and is also! adivision of-my copend- 'ing application, Serial No. 677,667,"filedv November 30, 1923.

to, produce the neces ated as Patent No. 1,533,840, of April 14,

vTheadvantages of thepresent invention arisefrom a condenser construction in which ready access to all of the parts is permitted.

I claim:

1. A jet condenser having an inlet chamher, a surrounding water box provided with a plurality .of nozzles arranged to discharge into the inlet chamber, said box having abottom wall provided with a plurality of hand holes giving access to the. water box and its nozzles, and a removable. hand hole plate normally closing each of said holes,

substantially as described.

2. A ,jet condenser" having aninlet cham a surrounding. water box providedwith of'water discharge means ara pluralit I discharge into the inlet chamber,

ranged to a. removable hand hole 4 10 into the inlet chamber,

n A said boX having a Wall provided with a plurality of hand holes giving; access to the Water box and to said spraying means, and

plate normally closing each of said holes, substantially as described.

3. A jet condenser having an inlet chamber, a surrounding water box provided With a plurality of nozzles arranged to discharge said box having an overhanging bottom Wall, a plurality of hand holes in such Wall giving access to the Water box and its nozzles, and a removable hand hole plate normally closing each of said'l holes, together with erabs' loeat'ed Within the Water b'oX and securing said plates, substantially as described.

In testimony whereof I have hereunto set my'hand.- a 3,
